Abstract: A composition for topical administration to an epithelium is disclosed. The composition comprises a deconstructed matrisome including one or more enzymatically fragmented peptides derived from biological tissue. The composition further comprises one or more pharmaceutically acceptable or cosmetically acceptable excipients. The deconstructed matrisome may be fragmented through degradation by one or more enzymes to produce the one or more peptides. The one or more peptides may be configured to retain cell signaling ability, thereby promoting one or more of tissue homeostasis, tissue repair, and tissue regeneration. The composition may be used to treat a tissue such as skin tissue exhibiting scarring, acne, eczema, psoriasis, and other skin conditions.

Abstract: An in vitro cell culture substrate is disclosed. The substrate comprises a decellularized tissue-specific extracellular matrix, wherein the tissue-specific extracellular matrix is derived from fibrotic tissue. A method of method of assessing an in vitro fibrotic cell culture is also disclosed. The method comprises providing one or more substrates comprising decellularized tissue-specific extracellular matrix derived from fibrotic tissue, where each substrate is provided in segregated manner. The method further comprises culturing native cells in each substrate to form a fibrotic cell culture. The method further comprises assessing at least one characteristic of each fibrotic cell culture.
